I noticed something wrong with WNED's PBS HD feed almost immediately after Rogers switched to it from Spokane in late April '06. I guess WNED never really cared about the HD picture quality, but rather tried to cram a couple SD subchannels into the WNED ATSC broadcast. It's a shame IMO, that Rogers can't get a decent full bandwith PBS HD feed to supply to its subscribers.

Joe (PBS) called me today and we had an excellent discussion for about 20 minutes.. They are monitoring this via 13" professional monitors. No wonder they can't see it.. My 61" TV is over 20 times as large.

He said they'd try to see if they can see the problem. I advised him it's also on true HD stuff like Cousteau, Springsteen, etc, so as far as I'm concerned that blows his upconversion hypothesis. I basically said what I needed to say directly to him.

For Rogers customers, perhaps we need to bug Rogers to give us Spokane back. More bitrate and no logo, make for better PQ..

I took quite a few pictures of the ghosting on the weekend, on several programmes. The ghosting is a huge issue, which is very clearly present on the pictures I have for HD and WS programming. I sent the photos to PBS today. I'll advise when/if I hear back.

We have re-started our HD Encoder, statistical multiplexer and satellite receiver in a first attempt to rectify this problem. We are now attempting to distill any changes that we have made to this
system in the last month or so to try and firgure out what is causing this. Your input is greatly appreciated!

Have been getting severe ghosting on WNED Buffalo - Toronto for the past few weeks here in downtown Toronto. See it both thru Rogers Cable 3250HD set top box and with OTA antenna coming off the CN Tower. That would seem to indicate that the problem is not with Rogers. When I first got my LCD HDTV and HD cable in early April PBS looked great. Something has changed somewhere since then.

I saw the ghosting the other day.....it was a concert but I think it was widescreen. The camera was on a relatively slow pan. I read in another forum that this is because of lack of bandwidth for HD. I don't think its macroblocking.

As I've said before, other than this problem the PQ has been great...certainly better than Spokane or Detroit.

I watched a gardenning show today and did see some ghosting and also some flashing when there was slow panning over a lot of detail such as very small rocks or branches. This seems to be a relatively new thing. It certainly wasn't there when we got the other HD PBS stations.
